Abstract: A power storage device has a power storage element and an electrolytic solution. The power storage element includes an anode body, a cathode body opposed to the anode body, and a separator interposed between the anode body and the cathode body. The separator includes a separator base material and a conductive polymer deposited on the separator base material. The power storage element is impregnated with the electrolytic solution. The separator has a first surface layer, which includes a first surface opposed to the anode body, and a second surface layer, which includes a second surface opposed to the cathode body. The first surface layer has a first region in which the conductive polymer is deposited, and the second surface layer has a second region in which the conductive polymer is not deposited.

Abstract: An electrical storage device includes an electrical storage element and an electrolytic solution. The electrical storage element is formed of an anode body, a cathode body facing the anode body, and a separator interposed between the anode body and the cathode body. The separator includes a separator substrate and a conductive polymer adhering to the separator substrate. The electrical storage element is impregnated with the electrolytic solution. The separator includes a first surface layer having a first surface facing the anode body and a second surface layer having a second surface facing the cathode body. The first surface layer includes a first region that is not provided with the conductive polymer, and the second surface layer includes a second region provided with the conductive polymer.
